It works!

I recently got into magnesium for a calming supplement after trying it many years ago and not feeling a difference. I finally gave it a fair shot and it works great! My body chemistry may have changed with age but it works so well for me now and this particular brand I was truly impressed with how effective it was. I am so happy it doesn't contain melatonin because I am not a fan of that and the grogginess that comes with it. The taste is decent and it mixes well with liquid and come with a scoop for easy measuring.

So far so good! Nice flavor, natural ingredients �

I love the natural ingredients in this product! I don’t have a lot of experience with magnesium but my sleep does feel more restorative! The flavor is very strong (but tastes good) so either add more water or use less than a full scoop of strong flavor is not your bag. Container and scoop store well, no concerns there.

Good product. Works perfectly

This product works pretty well! The flavor is not my favorite because I don’t really like cherry. But it’s not that bad I like to take it at night before bed and helps me with my mood and sleep. The dissolving is amazing pretty fast. And the packaging is great taste fresh.
